Terms & conditions.
A short summary of the standing terms that apply to engagements with Critical Asset Drone Inspections.
Last updated 30 April 2026
1. The agreement
Every paid engagement is governed by a signed Statement of Work or Services Agreement setting out the scope, deliverables, price, timeline and responsibilities of both parties. These website Terms are a short public summary — the contract is the document of record.
2. Scope boundary
Our flagship Site Security Vulnerability Assessment and all related intelligence work is delivered under a clean scope boundary. We do not test, validate or authenticate with credentials identified during an engagement. We do not carry out penetration testing of client systems. If intrusive cyber testing is required, we recommend that the client instruct an appropriately accredited cyber provider, such as a CREST-accredited firm.
3. Operations & safety
All drone flights are operated under our CAA Operational Authorisation (PDRA01-28445). Each engagement includes pre-flight airspace checks, landowner permissions, NOTAMs where required, and a site-specific risk assessment. We carry £10m public liability insurance.
4. Payment
Flagship Assessment engagements are billed at the fixed-price tier agreed in the Statement of Work. Other drone work is billed against the fixed-price quote issued after scoping. Invoices are payable within 14 days of issue unless otherwise agreed.
All prices quoted on this website, in proposals and in Statements of Work are exclusive of VAT. VAT is charged at the prevailing UK standard rate where applicable. Critical Asset Drone Inspections Ltd is registered for UK VAT under number GB 519 2696 62.
5. Deliverables & intellectual property
On full payment, the client receives the deliverables set out in the Statement of Work together with a non-exclusive licence to use them for the purposes described in the engagement. We retain copyright in underlying methodology, report templates and toolchain components.
6. Confidentiality
Engagement materials, site imagery and findings are treated as confidential. We will not disclose them to third parties without written consent other than as required by law, regulatory request or a court order.
7. Liability
Our liability under any engagement is limited as set out in the Statement of Work. Nothing in these Terms limits liability that cannot be limited under English law.
8. Governing law
These Terms and any engagement are governed by the laws of England and Wales. The parties submit to the exclusive jurisdiction of the courts of England and Wales.
